IMPROVEMENT IN MACHINES FOR CREASING FLUTED FABRICS.

Specification forming part of Letters Patent No. 171,264, dated December21, 1875; application led i A September 3, 1875.Y

` To all whom it may concern Be it known that I, JOHN EL BROWN, of NewYork city, New York, have invented certain new and useful Improvementsin Machines for Pressing or Creasing Flutings, which improvements arefully set in the following specification, reference being had' 'to theaccompanying drawings.

l In the method heretofore practiced for pressing or creasing flutings anarrow metallic edge space, under the pressing-iron as the operation isperformed on each section of the length of the iiuted fabric; and it isalso defective because the flute which is crushed down will sometimesfall forward, and sometimes backward, producing an irregular appearancein the goods. My machine greatly facilitates the operation, and at thesame time produces a much lnore perfect result. e

In the accompanying drawings, Figure l is a plan of my machine. Fig. 2isa sect-ion in elevation at the line Y Y, showing also the gearing inelevation. Fig. 3 is a section at the line ce x. 4 4 i The same lettersrefer to similar parts in all the drawings.

Gis a hollow cylinder revolving upon an axis supported by a bearing inthe frame of the machine. In the interior of this cylinder heat may beapplied either by a gas-jet or other appropriate means. A is apresserroller, having a cylindrical surface at h. This presser-rollermay be made hollow, and may be heated by a gas-jet or other appropriatemeans. This presser-roller is mounted upon a revolving shaft, which isdriven by a gearwheel, a', from a corresponding gear-wheel, c, on theshaft of the cylinder O. The shaft of the presserroller A is supportedupon a lever, g, which vibrates around a center, g4, so

placed as to permit a slight, nearly vertical,

movement to the presser-'roller A. Through this lever a set-screw, g1,passes, vhaving a recoil-spring, g3, between its head and the top upon avibrating beam, which is centered e at K upon the lever L, which iscentered also on the frame ofthe machine at L. The upper end of thislever is provided with a screw, Z, whose office isto'tighten or loosenthe bands which pass'over the band-wheels by moving the lever L awayyfrom or toward the cylinder and presser-roller, as required. When this'set-screw is tightened, the beam, which sup* ports the two wheels B andD, accommodates itself to the length of the bands, and assumes thepositionwhich will make the tension equal upon both bands. -it'and h hare narrowbands, preferably of metal. The band it h passes around thewheel B and the presser-roller A, and the band t' c' passes around thewheel D and the cylinder O. The centers ofthe baudwheels B and D arefarther apart than the centers of the cylinder O and presser-roller A,so that the bands converge as they approach the pressure-point betweenthe cylinder C and the presser-roller A. E is table, on

which the Work is received, and which leads up to the machine, and itssurface is about level with the top of the band-wheel D. On the top ofthe plate E are two parallelguides, M and M', attached to bars 1 l, inwhich are slots m1, through which pass the screw-pins m2, by means ofwhich the guides` M M are I held fast to the plate E, and by looseningthe screws m2 the guides M M can be moved backward or forward throughthe slots m inthe bars m'.

The operation of the machine is as follows: It is set in motion by acrank or other means in the direction of the arrows 111 Fig. 3. A lengthof fluted fabric, which it is desi-red to press or crease permanently,is fed into the machine onlthe table E between the guides M M', so thatit can be caught between the converging bands h h 4and c' i, and carriedalong with them toward the cylinder O. As the goods advance in themachine the flutes Q' l ViiLLi are pressed down between the convergingbands almost vertically, so that they will be symmetrically andsimilarly laid; and as the presser-roller Apresses down the folds uponthe cylinder C they receive a permanent set or crease. The guides M M.serve not only to keep the fluted fabric in proper position while it ispassing between the bands, but they also serve to hold back theiutedfabric and regulate, to some extent, the speed with which it passesbetween the cylinder C and the lpresser-roller A. By proper mechanism,`

when desired, a gum-cord can also be fed under or above theliutedfabric, or both above and under the same, and between the cylinder C andthe presser-roller A.

vIt is obvious that the mode of operation ofl thismachine maybeextended, so as t0 have several pairs of bands moving in the samemachine, each pair making a. separatev press-- nre or crease in thefluted fabric, which is,

passing through the machine, intervals being left between the bands forthe passage of the partsof the` uted fabric, which is, not-to bepressed.

What I claim as my invention, and desire to secure by Letters APatent inamachinefon creasing flutedfabrics, is-

1. The endless bands hh and M in combination with the presser-roller A.and cylinder:

C, and the Wheels B and D, when constructed and-arranged to operatesubstantially as and for the purpose set forth.

2. In'a machine for creasing iluted vfabric the combination of thecylinder C with the presser-roller A, mounted upon a movable center andcontrolled by a spring for the purpose of varying the pressure, asdesired, substantially as described.

3. The band-rollers B 'and D, mounted on opposite ends of a Vibratingbeam, forthe purpose of equalizing the tension of the bands,snbstantiallyas described.

4. The band-wheels B and D with the lever L and the screw l, combinedand arranged substantially as described.

5. In amachine for creasing uted fabric the :combination of i thepresser-wheels A and C, geared with the band-wheels B and D,substantially as described.

6. In a machine for creasing iuted fabric the combination of the table Ewith the bandwheels B and D., substantially as described.

7. Iii-amachine for creasing liuted fabric the combination ofthe table Ewith the guides M M, substantially as described.
